Geometrical aspects of solid solution separation by evaporation‐condensation driven in a closed system by a small temperature difference

Evaporation‐condensation driven in a closed system by a small temperature difference has demonstrated its ability to deliver semiconducting IV‐VI and II‐VI solid solution crystals of highest compositional uniformity. Geometrical aspects of solution component distribution emerging in the crystals grown in the near equilibrium evaporation/condensation systems are considered in this paper. The conclusion is drawn that no increase in the range of compositional variations with increase in the crystal size is to be anticipated. (© 2004 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
